Let's divide 21689038 by 684
We want to figure out the number of times 21689038 can be divided by 684.

Moving on to step 1:
684 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 684

On to step 2:
The number 684 fits into 21 0 times, leaving a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Take the next digit (6) from the dividend and append it to 21, then repeat: 216 / 684

Going ahead to step 3:
684 can be fit into 216 0 times, resulting in a remainder of 216.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 216 and we're left with 216.
Grab the next digit (8) from the dividend, add it to 216, then carry on: 2168 / 684

Step 4:
2168 divided by 684 is 3 with a remainder of 116.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 116 after subtracting 2052 from 2168.
Append the next digit (9) from the dividend to 116 and continue with: 1169 / 684

On to step 5:
If we divide 1169 by 684, we get 1 and a remainder of 485.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
If we subtract 684 from 1169, we get 485.
Append the next digit (0) from the dividend to 485 and continue with: 4850 / 684

Let's proceed to step 6:
The number 684 fits into 4850 7 times, leaving a remainder of 62.
Record the quotient 7 as the next digit in the result. 
Result so far: 317.0
Subtracting 4788 from 4850 leaves us with 62.
Bring next digit (3) of the dividend behind the 62 and repeat the process: 623 / 684

On to step 7:
684 goes into 623 0 times with a remainder of 623.
Use 0 as the next digit of our solution. 
Result so far: 3170.0
Subtracting 0 from 623 leaves us with 623.
Fetch the next digit (8) from the dividend, attach it to 623 and continue: 6238 / 684

Step 8:
6238 divided by 684 is 9 with a remainder of 82.
The next digit of our result is 9. 
Result so far: 31709.0
The remainder is 82 after subtracting 6156 from 6238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 9:
When dividing 820 by 684, we get 1 with a remainder of 136.
Put 1 as the next digit of the answer. 
Result so far: 31709.1
The remainder is 136 after subtracting 684 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Advancing to step 10:
When dividing 1360 by 684, we get 1 with a remainder of 676.
The next digit of our result is 1. 
Result so far: 31709.11
Subtract 684 from 1360 to get 676.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6760, and continue the process.

The final result is 31709.11 with a remainder of 0.676.
